FAQs
Install the motor on a flat, rigid base using the 365TC frame’s feet or mounting surface. Align the shaft with the driven equipment, ensure proper belt or coupling clearances, and secure the C-face drive end flange. Use appropriate fasteners and verify electrical connections match 230/460 V, 60 Hz, 3-phase supply. The OPSB enclosure provides protected access, simplifying field wiring and servicing.
The motor delivers 75 HP with a rated speed of 1775 r/min at 230/460 V and 60 Hz. It is a 3-phase device with a service factor of 1.15, insulation class F, and IE2 efficiency. Rated current sits around 170 A shaded (high) and 85 A (low) depending on voltage, with a 365TC frame and shaft diameter of 2.38 inches.
Yes. The design supports continuous duty with a 60 minute duty rating and a service factor of 1.15, which provides overload tolerance during peak loads. The OPSB enclosure and 365TC frame aid reliable operation in typical conveyor and pump installations, while the 230/460 V, 60 Hz configuration aligns with common plant power systems.
This motor carries CSA, CSA EEV, and UR certifications, indicating compliance with stringent North American electrical safety and reliability standards. It also references a NEMA B design and general purpose motor classification, which supports predictable performance in regulated manufacturing environments and simplifies supplier qualification and audits.
The C-Face drive end flange and 365TC frame offer straightforward mounting compatibility with standard bases, couplings, and motor bells. This reduces retrofit complexity, shortens commissioning times, and improves vibration damping and alignment accuracy—critical factors for durable performance in general purpose open motors used across conveyors, fans, and pumps.
